Answer:

5/32768

Step-by-step explanation:

This sequence does not have a common difference, but does have a common ratio of r = 10/40 = 1/4. The first term is a1 = 40.

The general term of a geometric sequence is ...

an = a1·r^(n-1)

Then the 10th term is ...

a10 = 40·(1/4)^(10 -1) = 40/4^9 = 5/32768

A number picked at random from the numbers 1 through 15 is prime. This "question" is on my study guide for Unit 6 Probability an

Sphinxa [80]

Solution:

we are given that

A number picked at random from the numbers 1 through 15 is prime.

As we know the number between 1 and 15 which are primes are listed below

2,3,5,7,11,13.

Here total number of favourable outcomes are 6.

The numbers 1 through 15 are as below:

1,2,3,4,5,6,7,8,9,10,11,12,13,14,15.

Here total number of possible outcoes are 15.

Hence the probability that if a number picked at random from the numbers 1 through 15 is prime $=\frac{6}{15}=\frac{2}{5}=0.40$

Hence the probability that if a number picked at random from the numbers 1 through 15 is prime is 0.4

Write the conversion factor for converting meters to centimeters

posledela

Since we are converting meters to centimeters we are converting large to small.

Expect the answer to be a larger number. Here are some example of large to small:
2 weeks (larger unit) = 14 days (smaller unit) 14 is larger than 2
4 days (larger unit ) = 96 hours (smaller unit) 96 is larger than 4
Since there are 100cm in a meter, when we change meters to cm, we need a bigger number. The conversion factor is 100 and should be used as a multiplier.
Example: 47m x 100 = 4700 cm
